Listers,
N 5800 has about 15 hours now. Test period is 25 hrs. I've played with Vso
and top end etc.
I need some corelation on fuel capacity, unusable, and burn rate.
I think I have 52 gallons max (bigger HR tank skins) ?
2.5 gallons unusable each tank, eh ?
14.5 gph at 20"/2300 rpm giving 190 mph indicated at 3500'msl (ballpark
speed confirmed by GPS)
I get some backfiring at random moments... and always when chopping for
flare-out.
Whats that all about ? Right now, it runs pretty warm, SoCal OATs were 60
to 80 F.
Mineral oil temp is around 200 +-10 and is sensitive to OAT. All EGTs line
up and CHTs arent too bad. No.1 runs cool on CHT.
When heat soaked on ground (and cruising) it shows signs of vapor effect,
wiggles and lowering of fuel pressure... but it stabilizes with shot of electric
pump.
Anyone care to compare ?
John Meyers

John
I have a HR2 with large tanks and can add about 27 gal. to a tank when I
blow it out. So I don't think you can have 2.5 gal. unusable.
I put heat risers on both front cylinders to keep cylinder temps. more
uniform.
I also get popping when I pull the throttle back for landing.
Regards
Bryan Carr
